So here is one of the updated faq's from the warhammer rulebook FAQ section:
Q:Does a TO WOUND roll of a 1 always fail to wound?
A:No. Though it is very rare for a model to be able to wound on a 1+
Imagine this: Flaming sword of ruin is cast on a unit of sword masters, who have entered combat against dark elf warriors with spears. The sword masters hit on 3's (with a re roll) and then wound on 2's (strengh 5 vs toughness 3) normally the sword masters require a 2+ to wound, but flaming sword increases the wound roll by +1 and according to the faq a 1+ would wound automatically since a roll of a one on the roll to wound will not always fail when it requires a 1+.
There you go, one of the most basic concepts of the game has become rediculous.
